I ordered tartan fabric, 7 meters of double width 13 oz, from Scotland and had it shipped directly to the kilt maker in the U.S. I received an email from DHL's customs prescreening that a better description is needed. The waybill only says fabric. I'm trying to best describe it for ease and cost effectiveness of import . Does anyone know what heading/subheading of the tariff schedule tartan wool fabric falls in, and what could I be looking to pay for a duty fee?
